looking for a M4 profile/style upper (complete with Bolt, carrier, handle, etc).
CMMG, Stag, RRA, etc all are good mfgs I am looking for.
NO Olympics or DPMS.
Preferably a USED upper, though I am open to a new mfg one if the price is right.
thanks in advance guys
oh and also, being I am in NY, a upper without a bayonet lug and a muzzle brake installed is fine with me also. If the upper has a flash hider and bayonet lug thats not a issue either, as I can modify the upper myself to be compliant before I assemble/install the upper onto the lower.
